The Hernandez family had just finished buying produce and other groceries when they heard about the mouse video.

"I think that's pretty gross, and I hope that they clean everything and replace everything because who knows how long that's been going on," Melisa Hernandez said.

In a statement by El Super, it said it has replaced all produce from the affected area and that it appears to be an "isolated incident."

"El Super is aware of the video footage ... and would like to reassure our customers that we have taken immediate corrective action. All produce in the affected area was removed from the shelves and discarded, and the area has been fully sanitized," the statement said.

Although some El Super customers said they are considering buying their groceries elsewhere, others said they are not surprised by the video.

"I'm pretty sure that this is not the only store that has it. So it's not going to bother me. Besides I wash all my stuff off anyway because I see the people with their fingers running over everything in the produce department. You have to be careful," Augustus Stone said.

CORRECTION: An earlier version of this story said the store was located in West Covina. The store where the incident happened was in Covina.
